Pipe 3 is also connected to the live-steam pipe 5' at a point lower and nearer to the engine than thc connection of pipe 1. E designates a short glass sight-tube through which the rat-e of working of the dcvice may be seen.

The operation of my device is more fully described as follows: .lhcreservoir A is lled -with oil and closed up tight above and below.

4 which entcrsthe sight-tube action of the water The valves C, K, H, and lI' are then all opened. New if the pipe 5 is filled with live steam the water from the condensation which accrues in pipe l passes downward through pipe-2 and passages 2, through the chamber A and'passage c', into the main reservoir A, settling on the bottom thereof, thus buoying the lubricant upward, forcing it through the passage c. where it meets the downward-passing water. It fills the chamber A, then forces its way through the passages Band throughthe valve c', and passes upward through the nipple e in the sight-tube E, in which it is joined with the warm circulation from the pipe 4', E by the space snrronndingalie nipple e, and the lubricant isjthus conveyed by the continuation of passages 3 into the pipe and finally discharged into the live-steam pipe.` If it is desired to shut oit' part or all ot, the ow of lubricant, the valve K is turned accordingly. It is evident that the condensation-water when the valve K is entirely closed off remains at a standstill in pipe 2 below its intersection with pipe 4, for'the pipe et, being left open, con- Veys away all of the condensation aforesaid and passes it through pipe 3 into pipe 5 in the same manner as when the lubricant-valve K is. open. This-is of importance for two rcasonsvffirst, it keeps the parts warm, as heretoforey stated, and, second, it prevents the head or pressure of condensation-water from rising, so as to produce greater pressure when started again than that which existed when the valve K was turned oli?. I thus secure a uniformity of pressure which has not been attained in lubrieators of this class,vtho condensation provided for in pipe Ibeing necessarily su'cient to keep the Vhead in pipe :2 at all times as high as the intersection with pipe l. When the device is to be refilled with lubricant, the turn-valve c is screwed down, so as to close the passage c. The plug C is then removed and the'pl'ug-cap 1) loosened, so as to drain all ofthe water out of the reservoir A,wi1en the reservoir may again be lillcd from the top with th lubricant to be used. During the process 'of 'filling the lubricant which remains in the chambcr A is displaced by the 1n pipe 2, thuseontinuing the liow of lubricant the same as whenudsing, When kA isfilled, the

the main reservoir. valve c is of course again .unserewe't I am aware that in lubricatorsof this kind a displacement cireulationhas been supplemented'heretofore by a conveying circulation, but they have not been so simplified as to conduct said circulations from the same l valve -con trolled passage between the source and provide foracontinuous ovcrllow for the coi'iveying circulation when the displacement circulation is shut olif. In my dcvice the two circulations are conducted from the saine level from thc same-source, and the disl'ilaccment circulation maybe cut olf without danger of changing hc head or pressure which controls the quantity of oil displaced.

Having thus described my invention, ,what I claim as new, and desire to secure by Letters Patent, is-

l. A lubricator of the kind described havingla displacement circulation and a conveying circulation, in combination with a condensing pipe or chamber supplying condensation-water forsaid circulations from a con mon point or level whereby equality ofpressure is maintained in the said displacement circulation, substantially as described and for the purpose set forth.

L. A lubricator of the kind dcscribedusng condensation-water for displacing and conveying of lubricant to the point required, and having a main oil receptacle or reservoir into which vdisplacement-water is conducted, i n combination .with a supplemental chamber c" reservoir through which 111e entrance of s: displaccmcnt-Water and exit'of lubricant:k made, a substantially. vertical passage hctwcen the said two reservoirs, a valve by means ot which said passage may be closed so as to suspend the passage of condensationwater into the main reservoir during replen-- ishment of the same and the saidsupplemental reservoir adapted to receive the displacement circulation and continue the llow of lu bricant during the said operation of replenishment substantially as specified.

3. In a lubricator of the kinddeseribed' a displacement circulation and a conveying circulation, and a common condensing pipe or chamber adapted to supply both circulations, an oil-chamber adapted to receive the condensation-watcr ot' the said displacement circulation as it displaces the oil, and a passage til-om said chamber adapted to conduct the displaced oil intosaid conveying circulation, and the head orl'ircssure l'or said displacement circulation adapted to be maintained at an equality by overflow into the conveying circulationfromthe common condensing-pipcaforcsaid, snhstmitiallyas specilied. n y

l. In a lubricalor ol lhc kind described a displacement circulation, a secondary circlilalion adapted to convey the oil or lubricant and provide an overflow for surplus condensation-water the said secondary circulation and displacementcirculation bcingcondlu'tcd froml a common level lin a common condens ing chamber or pipe, a,conde:Ising-chamber adapted .to provide condensation-watcr for saidcirculation, a main reservoir anda supplemcntal reservoir through whiclrfsupplemental reservoir the displacement circulation aforesaid enters the mann reservoir mnd n said re8- y scopes :i

veying circulation, the said circulations origi nating in a common condenser, a condenser for supplying said circulations, and means for suspending the said displacement circulation by deiecting the surplus condensation-water into the conveying circulation without raising the levelor pressure of the head therein, sub" stantially as specified.

6. yIn a lubricator the combination of a main reservoir and a supplemental reservoir, a passage connecting,r the same and a Valve c exy tending through the supplemental reservoir and adapted to close the said passage, with means forconductingcondensation-waterinto and oil out of the said reservoirs, substantially as specified.

7. In a lubricator the chambcr A and supplementary chamber A with a passage c connecting them, together with means forY conf ducting ,water into and oil out of said maini chamber through the supplemental chamber, and means for closing said passage so as to permit of a similar circulation of oil and'water in the supplementary chamber during a relling of the main chamber, substantially as and for the purpose set forth.

8. In a lubricator the combination of a bracket having passages for condensation-water and lubricant, la supplemental chamber with.. which said passages communicate, the said supplemental chamber communicating with a main chamber through a passage adapt ed to be closed without suspending the circulations aforesaid, together with a mainchamber or receptacle for lubricant and means for conveyingthe same to the place where required, substantially as specified. n
